Acting as your Onsite
Temporary Works Coordinator

At CDM 365, our experienced Temporary Works Coordinators (TWC) provide clients with complete confidence that all temporary works are properly planned, managed, and controlled. From scaffolding and formwork to complex structural systems, we ensure full compliance with BS 5975 and industry best practice. We oversee contractors, review and challenge designs, carry out thorough risk assessments, and conduct regular inspections—protecting both your workforce and your programme.

With extensive experience across civil engineering, oil and gas, steel, rail, nuclear, and COMAH Tier 1 and Tier 2 heavy industries, we understand the complexities and risks involved in high-hazard environments. Our proactive approach minimises risk, prevents costly delays, and ensures your temporary works are delivered safely, efficiently, and in full compliance throughout the entire project lifecycle.

Key Responsibilities of CDM 365 as your Temporary Works Coordinator

Coordination and Planning

Temporary Works Planning: The TWC oversees the planning and coordination of all temporary works on the site. This includes identifying what temporary works are needed, when they will be required, and how they will be integrated into the overall construction process.
Liaison: They work closely with designers, contractors, and site management to ensure that temporary works are designed and implemented in line with the project's requirements and safety standards.

Appointment of Competent Personnel

Design Check: The TWC is responsible for checking that all temporary works designs are adequate and that they comply with the necessary safety standards and regulations. They may review design calculations, drawings, and specifications.
Design Approval: Before construction, the TWC must approve the temporary works design, ensuring that it is fit for purpose and safe to implement.

Communication and Documentation

Temporary Works Register: The TWC maintains a register of all temporary works on the site, documenting their status, design details, and approval dates. This ensures that all temporary works are tracked and managed properly.
Briefing and Coordination Meetings: The TWC organizes briefings and coordination meetings to ensure that all relevant personnel understand the temporary works' requirements and safety considerations.

Modifications and Alterations

Managing Changes: If there are any modifications or alterations required to the temporary works during the construction process, the TWC is responsible for ensuring that these changes are properly designed, approved, and implemented.
Re-approval: The TWC ensures that any modifications to temporary works are re-approved by a competent person before being put into use.

CDM Design Risk Management

Hazard Identification: The TWC identifies potential hazards associated with temporary works and ensures that risks are mitigated through design and planning.
Emergency Planning: They may also be involved in developing contingency plans for emergency situations related to temporary works, ensuring that the site is prepared for unexpected events.

CDM 365 working with BS 5975.2024 Design Check Categories:

Category 0 (CAT 0):
- Complexity: Very simple, straightforward designs with minimal risk.
- Checking Requirements: Basic check, typically performed by the designer themselves.
- Examples: Simple formwork, proprietary systems where the design is following manufacturer's guidelines.
Category 1 (CAT 1):
- Complexity: Standard, straightforward temporary works where failure or incorrect use could pose a limited risk.
- Checking Requirements: The design is checked by someone other than the original designer, typically within the same organization. The checker should be competent and independent.
- Examples: Standard scaffolding, and simple trench supports.
Category 2 (CAT 2):
- Complexity: More complex temporary works where failure could pose a significant safety risk, but the design is still considered standard practice.
- Checking Requirements: The design is independently checked by someone with sufficient competence who was not involved in the original design. The checker may be from the same or a different organization.
- Examples: Complex falsework, excavation supports requiring bespoke design.
Category 3 (CAT 3):
- Complexity: Highly complex or innovative designs, where failure could result in serious consequences, and where the design is not based on standard methods.
- Checking Requirements: An independent third-party check is required, typically by an organization completely independent of the original design team.
- Examples: Complex scaffolding, temporary bridges, large cofferdams, and works involving a high level of innovation or risk.
